Question: How to access the data from musicapi.search_playlist function?

[TimG233]

我尝试去搜索一个playlist通过关键词，但是他不能像musicapi.search_music 一样去操作 (变成list)，否则会有报错。目前这个不确定是我的操作有问题还是程序有Bug 代码：

# after login
search_playlist = await musicapi.search_playlist(key="古风", page=0, limit=5)
print(search_playlist)  # (531, <generator object Music163Api.search_playlist.<locals>.<genexpr> at 0x0000029BC0970AC0>)
search_playlist = list(search_playlist[1])
print(search_playlist)

报错：

Traceback (most recent call last):

    asyncio.run(netease_search())

    return data["result"]["playlistCount"], (PlayList(playlist_data) for playlist_data in data["result"]['playlists'])
  File "... \venv\lib\site-packages\pycloudmusic\object\music163.py", line 418, in __init__
    self.tags = playlist_data['tags']
KeyError: 'tags'

经过测试，Playlist这个class (\object\music163.py) 里的playlist_data不一定会有以下这些 （根据不同的playlist）

• tags (包括tag_str)
• subscribedCount
• createTime
• music_list 这些如果playlist_data里没有就会扔出KeyError所以感觉做个defensive coding就好 比如说 self.tags = playlist_data['tags'] if 'tags' in playlist_data else None

因为搜索出来的数据不完全，所以分成了不同的类，可以使用 id 再次请求获取完整数据

[FengLiuFeseliud]

应该返回的是 ShortPlaylist 对象，可以先改一下库代码，晚点修一下，没注意

[FengLiuFeseliud]

也可以先用 musicapi._search

修完了 更新至 v0.1.4.5 可以正常使用

from pycloudmusic import Music163Api
import asyncio

async def main():
    musicapi = Music163Api()

    for playlist in (await musicapi.search_playlist(key="古风", page=0, limit=5))[1]:
        print(playlist.name, playlist.id)

    print("=" * 50)

    # 搜索数据没有 tag 获取完整歌单再获取 tag
    for splaylist in (await musicapi.search_playlist(key="古风", page=0, limit=5))[1]:
        playlist = await musicapi.playlist(splaylist.id)
        print(playlist.name, playlist.id, playlist.tags_str, playlist.tags)

asyncio.run(main())
